Result

Tested as per CAN/ULC-S741-08 with five 1-m2 membrane specimens and measured for air permeance at a minimum of six air pressure differentials (ΔP) between 0 and 300 Pa – Unconditioned (Prior to UV and Heat Aging).

Air leakage rate at 75 Pa ΔP (based on linear regression of 30 data points) ≤ 0.02 L/(s·m2)

0.0036 L/(s·m2)

Five 1-m2 membrane specimens tested and measured for air permeance at a minimum of six air pressure differentials (ΔP) between 0 and 300 Pa – Conditioned (After UV and Heat Aging).

Where less than 0.01 L/(s·m2) for unconditioned specimens, the increase of the air leakage rate at 75 Pa ΔP for conditioned specimens ≤ 0.001 L/(s·m2).

0.0046 L/(s·m2)Footnote (1)

Water Vapour Permeance (Infiltration Direction)

When less than 60 ng/(Pa·s·m2), the location of the product installation is restricted by the requirements listed in Article 9.25.1.1. of Division B of the NBC 2015.

332 ng/(Pa·s·m2)

Water Vapour Permeance (Exfiltration Direction)

373 ng/(Pa·s·m2)
